Specification of Letters Patent.

Patented Feb. 3, 191%.

Application knee March 31, was. Serial' no. 75mm;

"To all whom it may concern."

lrle it known that I, THOMAS F. lnnnson, a citizen or the United States, residing at llillerica, in the county of Middlesei: and

, State of Massachusetts, have invented cernilv device may be made small and compact and at the same time without any fine scales or gradnations which might rnske it d'il'ficnlt to handle. It may be made with dillercn-t scales for different purposes.

In the drawings, Figure 1 isen elevation. Fig. 2 is an elevation with parts broken away to show the interior construction. Fig. 2, is view from the top on line XY of Fig. 1. Fig. 4: is a viewfrom the top on line S i. of Fig. 1. Fig. 5' is a view from the 03 on line U-V of Fig. 1. Fig. 6 is a View from the top on line VW-Z of Fig. 1.. l igx- 'E- is s View from the top on line OP of 1. ln Figs. 3,4 5', 6 and 7 the parts broken away or shownin section in Fig. 2 are shown complete and in place.

The principal features of my device are a casing [hwhich is relatively stationary; o barre B revolnble in the casing and which has longitudinal slots 22; a, threaded spindle LT which is revoluble with the casing A or stetibnary therewith; a ba'nd or marker D slideble on barrel B and arranged to en gage the threads of spindle C whereby when the barrel B" is rotated, marker 13 will be forced by its engagement with the threads of spindle G to slide back and forth. I also provide a Ctlp F rotatable i'n casing'lll preferably in the same direction with barrel B.

The casing A is preferably tubular and is divided by a transverse partition 10 as shown in Figs. 2 and 4:. This partition, has an opening 11 which'con'forms to theshape of spindle C which at that point is flattened or cut away on opposite sides whereby it can not turn in opening 11. If dollars and cents are to be registered, at its bottom,

casing provided with twenty teeth 12 which rake toward the right as shown in Fig. 1. It also has a pointer 13 which in dicctcs a. tooth which corresponds with the zero of the device. At the top, its circurhfcrcnce. is divided into five equal parts by notches 14, four of which rake toward the right, while the fifth which is in line with pointer 13 is a locking notch- 15 With parel;

lel sides.

' The barrel B is off-such size as to fit revolnbly inside of casing A and at that end has a collar 20 which encircles it and is p'refembly soldered or briized into place. The edge of collar 20 adjoining teeth 12 oi ing A is formed with twenty teeth 21 w engage teeth 12 and rake toward the le These teeth are nu'nibe'red as shown, ere-i erzibly'from zero'represented by the dollar sign, in 5s and 10s up to 100. At the opposite end, barrel B carries another colhilr or pencil holder H which is preferably soldered thereon. It has a scalewhich may be from zero to fifty marked lengthwise on one or both of the slots 22 which extend longitudinnlly through barrel B. Preferably' zero begins at the upper edge of holder H. Near the bottom of barrel B is a partition 2. which may be held in place by means of ears which enter depressions 26 in the Wall of barrel B. ill radial slot 2 permits the lower endof spindle C to he slid in place in the center of partition 24 while the parts are being assembled and before holder H is put in place. This partition serves as the bottom bearing for spindle C and partition 10 serves as the top'beari'iig. Preferably collars 30 and 3]. are fixed near the end of spindle C to prevent any loi'igitndinal action between spindle C and bin-rel B. Spindle C- at its lower portion 33 is cylindrical and is threaded'with a one in twenty pitch. It has at exactly the right predetermined place near the upper end of t-l'ietln'eaded portion 33' a finger 34 which extends outward and serves as a lock its will be described hereafter.

The marker D consists of a. band slidable on the outside of barrel B and provided with a catch which comprises {L push button or member 10 which extends through suitable openings in marker D and also through both slots 22 in barrel B. Near its middle portion, member 40 is formed as a ring 41 extending loosely aronnd'spindle C and adapted at one point to fit thethrcads thereof as shown in Fig. 6. A compression spring 42 normally tends to hold 4:1 in en gagenient with the threads on "C. By pressing on the cnd43 of member 40 which pref-- erribly has a slot for the receptionof the attached toring 41 in such a positionihat when marker D has risen 'to a predetermined point, nose 45 will strike finger 341 and prevent further turning.

Before Starting to usethe device, the parts 'are so adjusted that zero or the dollar sign on. the tooth scale of .collar 20 is turned to pointer 13 and the marker D is sli'd down until its lower edge coincides with zero on the slide scale marked along the length of slots 22 in. barrel B. The scale on 20 which I will call the tooth scale is intended to register the cents, preferably in 5s and 10s up to one dollar, while the scales along slots 22 which I'will call the slide scale is intended to register the dollars from zero to fifty.

To hold barrel 1; in engagement with casing A, I provide a collar or nut 3G fastened to'spindle C at'a point above partition 10, and between it and partition 1O I place a compression spring 37.. Barrel B may therefore be turned with the fingers as the teeth 21 ride over teeth 12 and lock themselves in place whenever the turning is stopped.

Cap F comprises an outside section 50 which is cylindrical, headed and knurled at 51 and of the same diameter as casing A against the end of which it' rests. The cap inside 52 its just inside of 50 and therefore inside of easing A and is attached to 50 by means of a screw 53 or by any other suitable device. Its bottom 54 has a circular openingto permit spindle C to turn therein. A washer having an opening which fits the flattened or cutaway portion of spindle C as shown in Fig. 3 revolvestherewith and serves as a bearing for compression spring 56 between it and a collar 57 fixed on spindle C. This spring and collar hold cap F elastically in engagement withthe end of easing A.

edgeof cap F has a single tooth 58 which fits notch'15 and which can readily be slid over and into notches 14. Cap F in connection' with marker tooth 58 and the scale 17 on the upper end casing A is used to countthe pennies for instance from one to five. When. five is reached, marker tooth 58 drops into notch 15 and indicates by the.

additional forcerequired to disengage it,

corresponding to five. In this way, .any amount from one cent to fity dollars can be counted.

In place of the holder H, any other suit;

able device may be used to limit the downward motiono'f marker D. The nose 45 is. so placed and adjusted as is also finger The end of casingA has notches 14 and 15 as described while the adjoining be turned one tooth 'cap'revoluble in the casing in mg the notches noes .755

34' that they will engage at the time when the bottom edge of the marker D has reached the upper limit or the 50 mark of the slide scale.

The casing A may be ornamented in any desired manner and may be of any desired form such as octagonal, etc. provided the working parts are not affected.

The tooth scale may run from one to ten for instance and the slide scale may bedivided with reference thereto. In such cases, the itch of the screw must be adapted to con orm. The parts may be arranged to count English money, pcltnds, shilling and pence, or they may be arranged to count any other money or things.

The cap F need not be used, if desired, be omitted entirely, but I prefer to use it. b

In using the device, cap F is naturally held in the left hand and barrel B in the right. Barrel B is turned from the operator or to the right in Figs. 1 and 2 and teeth 21 ride over teeth 12 against the action of both springs 56 and 37. When it, is desired to count cents on scale 17, the

hands are pulled apart and as cap F is acted on only by spring 56 while B is acted on by 56 and 37, cap F is pulled away from easing A and barrel B can be turned toward the operator. When it is moved in this directi0n, the oppositely pitchingteeth 21 and 12 engage and thereby casing A turns with B as far as the registration desired.
